使用 certbot 工具申请 LetsEncrypt 证书

certbot certonly -d <域名> --apache --register-unsafely-without-email --agree-to
root@ts:/etc/apache2/sites-available# certbot certonly -d azuresky.live --apache --register-unsafely-without-email --agree-to
Saving debug log to /var/log/letsencrypt/letsencrypt.log

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/azuresky.live/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/azuresky.live/privkey.pem
   Your cert will expire on 2023-12-31. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot

        server {
                listen 443 ssl;
                listen [::]:443 ssl;

                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

                         }
                        proxy_pass https://localhost:10443;
